github flavored markdown testing

colors

using [gfm latex] seems to be the only reasonable way to annotate with color (see [latex color docs]), although it does not seem to differentiate between serif (roman - textrm), sans (sans font - textsf), and mono (teletype - texttt), and colorbox is not supported, which seems to eliminate the possibility of background / highlight color.

method markdown result
latex text $\textrm{\color{cyan}{cyan text}}$ text text $\textrm{\color{cyan}{cyan text}}$ text
latex text $\textsf{\color{cyan}{cyan text}}$ text text $\textsf{\color{cyan}{cyan text}}$ text
latex text $\texttt{\color{cyan}{cyan text}}$ text text $\texttt{\color{cyan}{cyan text}}$ text
